Our extensive HVAC System Retrofit at Luther Memorial Church features designs to accommodate 12 different functions in this 40,000 sq.ft. 1923 Gothic cathedral. Project highlights include:
• Installation was concurrent with renovation, and included new heating, ventilation, and air conditioning
• The 60 ton chiller operates during off-peak electrical rates (storing 760 ton-hours of ice for peak cooling needs) and is a decoupled system with variable speed pumping throughout
• Three 94% efficient sealed-combustion boilers utilize a re-circulating pump only during occupied hours
• Five single zone air handling units (4 pipes each) have large face area cooling coils and small fan motors with excess air relief through economizer cycles rather than return fans
• Direct Digital Control (DDC) system is easily programmed by staff for ultimate comfort, optimal start, variable flow of fans and pumps without shutoff of individual terminals, functional ice storage and melting, and optimal boiler operation
